Abstract：Aiming at the problem that the loading device only has manual control function，the dynamic load characteristic of the high

power device's driving system was expounded. A set of designing methods about simulating controllable loading and testing's device was

put forward. The mechanical loading device base on magnetic powder clutch and permanent magnet synchronous motor，the upper

computer control interface，the control core based on Freescale 56F8346 DSP，the motor driving unit based on power electronics，the high

precision current sampling based on MAX1415，a excitation current source base on DC/DC switching circuit and the current detection for

excitation current source output based on hall current sensor were designed. At last，the hardware and software of this device was

developed. The experiment was worked out and the results show that the dynamic load's analog loading and measurement and control of

this exploited device is realized. It offers a important platform for the test of hardware and software and the performance analysis for high

power device's driving system.
